Approach

Applying the pinned theorem at n yields only a prime at or above n. This failure remains available as prior work for the next attempt.

Observed Lean run

The attempt records the work; the run records what happened when its file was checked.

Off-by-one proof attempt fails

hbound has type n ≤ p but is expected to have type n < p

What carries forward

The starting and updated context packs both retain this failure, so another contributor can see the obstruction.
